Dear Kandy

Try the below...in D9 and copy to the other columns upto O9

=IF(OR(MONTH(DATE(YEAR(TODAY()),MONTH($K$3)+4,1))= MONTH(D8),MONTH(DATE(YEAR(TODAY()),MONTH($K$3)+8,1 ))=MONTH(D8),MONTH(DATE(YEAR(TODAY()),MONTH($K$3)+ 12,1))=MONTH(D8),MONTH($K$3)=MONTH(D8)),1,"")

I am sure there should be a simpler one...

I need a formula that can calculate and issue the number 1 every four months
as above; using the start date to issue the first one.
